How can I access full source of a WebView
-
Hi
I am trying to send the contents of a webwiew with email. I have found
several ways to do that, but there are minor problems.
// get the attributes string of the webview
id res = (id <WebDocumentText> )[[[myWebView mainFrame] frameView]
documentView];
NSAttributedString *p = [res attributedString];
NSPasteboard *pb = [NSPasteboard pasteboardWithName:@"PBtoMail"];
// init a private pastebord for data transfer, this time use
webarchive for transfer
[pb declareTypes:[NSArray arrayWithObject:NSRTFDPboardType]
owner:self];
// convert the attributed string to rtfd and place it on the private
pasteboard
NSRange range;
range.location = 0;
range.length = [p length];
[pb setData:(NSData *)[p RTFDFromRange:range documentAttributes:nil
forType:NSRTFDPboardType];
// open mail window using the rtfd data using services...
NSPerformService(@"Mail/Send Selection", pb);
This works, but quality is no so good. So I tried a different approach
// init a private pastebord for data transfer, this time use
webarchive for transfer
NSPasteboard *pb = [NSPasteboard pasteboardWithName:@"PBtoMail"];
[pb declareTypes:[NSArray arrayWithObject:WebArchivePboardType]
owner:self];
// get the webarchive and place it on pboard
[pb setData:[[[myWebView mainFrameDocument] webArchive] data]
forType:WebArchivePboardType];
NSPerformService(@"Mail/Send Selection", pb);
This works better. However external CSS code is not copied, which
makes the page look different. When I select all and copy from the
webview manualy and then paste it on a new mail window it works fine,
the external CSS is copied as well. Is there any way I get the full
source (including the external CSS) so that I can place it on the
pasteboard?
Thanks in advance. -

In order to get the source of a WebView you'd do something like this:
DOMHTMLElement* el=(DOMHTMLElement*)[self
mainFrameDocument].documentElement;
NSString* source=el.outerHTML;
However, external CSS files are not part of the source of the page so
no method of obtaining just the source code will do this for you.
I suspect what is happening when you copy and paste into Mail is that
the WebView is placing a web archive on the clipboard, which contains
all the images and other linked resources.
You can get a web archive like this:
[[[webView mainFrame] dataSource] webArchive];
When copying to the clipboard you can specify the type as
WebArchivePboardType.

Thanks Rob,
I tried your way (DOMHTMLElement* el...) and it gave me the source.
Unfortunatly it gives only source and does not include external files.
I already tried your second approach.
[pb setData:[[[myWebView mainFrameDocument] webArchive] data]
forType:WebArchivePboardType];
I just found something intereting. I was wrong to think that the
external CSS is not copied in this way. I saved the Pasteboard as
webarchive, opened it from Safari, and looked at the source. CSS was
not there. On the contrary, webarchive produced by manual copy had the
CSS code. But then, I opened the webarhives as TEXT (using
subethaedit). The CSS code was PRESENT in BOTH of the WebArchive
files. Somehow Safari can not see the one produced by the above code.
Any other suggestions?
